You can structure your Structured Text program to separate your block of your code. It would help you to identify what you have coded in that specific region and enable you to navigate easier. 

Method 1 using commenting: 

////////////////////////////////////////////////////////						 
//Initialize the values							  
	(*your code here*)
////////////////////////////////////////////////////////						 
							   
////////////////////////////////////////////////////////						 
//Start the machine							  
	(*your code here*)
////////////////////////////////////////////////////////

After collapsing the descriptions, the code looks like this: 

Method 2 using pragma: 

{region "Description"}
// code
{endregion}	

{region "Initialize the values"}
// your code here 												  
{endregion}
													   
{region "Start the machine"}
// your code here 														
{endregion}	

"region" pragma allows you to create regions in your code.
